The story of the National Capital Trolley Museum is one of love, patience and quiet diligence. Streetcar service in D.C. ended in 1962. In 1959, knowing the system would soon meet its doom, streetcar fans founded the museum, which opened in 1969. Since then, they’ve kept the streetcar flame alive — to be rewarded, presumably this year, with the rebirth of streetcar service on H Street and Benning Road NE.
